GEORGE HOOKHAM, OF BIRMINGHAM, ENGLAND.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent N0. 787,669, dated April 18, 1905.

Application filed February 18, 1904. Serial No. 194,277.

To all whom, t mol/y concern:

Be it known that I, GEORGE HOOKHAM, a subject of the King of Great Britain and Ireland, residing at 7 and 8 New Bartholomew street, Birmingham, England, have invented certain new and useful Improvements in Bottle-Stoppers, (for which I have made application for Letters Patent sin Great Britain, No. 4,113, dated the 21st day of February, 1903,) oi' which the following is a specification.

This invention relates to improvements in bottle-Stoppers, and has for its object to provide an improved form of stopper for bottles and the like.

The invention further consists in forming bottle-Stoppers of material other than cork which is naturally compressible or which has been artificially rendered compressible, the body being entirely inclosed by protective capsules or treated with a suitable Waterproofing agent and either entirely unprotected by capsules or having its inner end closed by a capsule. f

Referring now to the accompanying drawings, which lllustrate forms of the invention to an enlarged scale, Figure 1 is a sectional elevation of a bottle-stopper constructed according to one form of my invention. Fig. 2 is a similar view oi another form in which the stopper is entirely inclosed by capsules. Figs. 3 and 4 are sectional plans illustrating the manner in which the paper body is made and rolled.

In carrying my invention into effect,as illustrated in Figs. 1, 3, and 4 of the accompanying drawings, a strip of corrugated paper t is rolled around a wooden core b, so as to form a cylinder. with cloth or the like e, which is in turn either partially covered with a metallic capsule c, as in Fig. 1, or entirely covered by capsules c and (l, as in Fig. 2. At the top of the stopper I bore or punch a small hole f, into which an ordinary corkscrew may beinserted forthe withdrawal of the stopper. Fig. 3 illustrates the coil loosely wound to show the corrugations; but it will be understood This cylinder is then covered:

upon itself to form a double layer, as shown r in Fig. 4, one end being shorter than the other. It is then wound into a double coil by means of a rod witha split end holding the paper. When wound, the coil is inserted in the capsule in such a manner that the rotary movement of a corkscrew inserted for the removal of the stopper shall tend to eX- pand the inner turns of the said coil tightly against the outer ones. By this means lateral displacement of the central portion of the roll when the stopper is being withdrawn by a corkscrew is prevented.

It is preferable to employ a capsule with the paper cylinder. If, however, a capsule is dispensed with, care must be taken that no axial hole remains. The hole may be plugged or the paper wound tightly upon a core, such as a cord, which remains part of the stopper, or thehole may be closed by longitudinal compression in a die.

In every case where the body or cylinder is not suitably inclosed in capsules I treat it with a waterproofing agent in any suitable manner.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A bottle-stopper in which the body consists of a roll of corrugated paper protected from the contents of the bottle, substantially as described.

2. A bottle-stopper in which the body consists of. a roll of corrugated paper protected from the contents of the bottle by a capsule over the inner end of the body, substantially as described.

. 3. A bottle-stopper in which the body consists of a roll of corrugated paper entirely inclosed by capsules, substantially as described.

4. A bottle-stopper in which the body consists of a roll of corrugated paper surrounded by a yielding substance and protected by a l In Witness whereof I have hereunto set my capsoul on its inner end, substantially as dehand in presence of two witnesses. sci-1 ec 5.
